Does the optimizer look into function called from query?
In my queries the expression (SELECT hwyl FROM Stock) / (SELECT regularPayment
FROM Stock), where Stock is a one-record table, often is repeated. The
optimizer sees that, and makes the ratio a constant, and I can afford to be
clear. If

You are not using NULL as the original concept of it was. NULL means that the
value is undefined or unknown.
That is quite true, especially in a table. But, almost from the beginning, NULL
was overloaded:
set @m = (select sins from emailinglist where

Okay, I've reviewed the online man page for date and time functions, and I've
played with several likely candidates, and I am still having trouble
subtracting two arbitrary Datetimes to get something that is useful. A simple
subtraction yields the least
equality. If I
write
IF A = B THEN
then if one is NULL and the other not, and the code is such that never are both
NULL, well, for my purpose they are not equal: so good. But if I write
IF A B THEN
often I want it NULL-safe, for if one is NULL and the other not, I want that

Here's a simple query: select name,status,min(dt), max(dt),count(*) from
mytable group by name I need an efficient way to get this data, along with the
status of the row with the max(dt). 'status' is not in the group by, so I get
apparently random statuses.

What it says, is If you are going to run many operations. You are updating
many rows, but you are only doing ONE operation: a single update statement.
For what it's worth, the downloading HTML help claims this only for MyISAM
tables, because between

workers and patrons to pay for that which formerly the company paid: forms,
instruction books, With online banking the bank pays fewer tellers. The
company s only bizness is to sell something, and after the sale vanish if may
be.

But it seems that there is no select ... into LOCAL file statement. Any
suggestion is appreciated.
Indeed: you can use only standard output.

takes less time than table (you have not shown your table code) only
because of the problem s size. If you had thousands of numbers the string at
first would be only slower, but with enough it would not work at all, because
you would reach MySQL s string-size limit.
A benchmark of repeatedly
with the connection.
I wrote an edit-distance function, and two procedures, that use temporary table
for array. The procedures s outcome was in the temporary tables. In routines
there are table-use restrictions, more in functions than procedures, and I so
wrote my function because of them.

Thanks guys for the help. but my problem seems to stand unsolved.
Right, no arrays. Nothing is left but table. I used a temporary table, but note
that MySQL also does not let table be returned, or passed in. The table-name
will be *sigh* global.

Thanks for your time reading my message, but I don't understand what
is the result context that you are talking about. Could you please
elaborate?
Well, if an expression is an argument to, say, CONCAT, the expression s
result is character string

Hi, I would like to create a function in Mysql that returns an Array of
Numbers. I am trying to run a big amount of stream of data on Mysql and I can't
afford the time to store the data into a table and retrieve it later.
Are there any arrays at all in
